The last few updates have been huge. You'll have to repeat what the tech did to get it to work to get it to work again. If it's nothing Samsung supports, you'll have to repeat what the crutchfeild tech did and hope no changes happened in the ISP modem or Samaung TV.
I lost the ability to view or listen to computer content ( music, photos, movies ) through my Samsung un65ks using a cat 6 cable from my modem to the TV. I simply added content to windows media playlist and selected play to then selected either the TV or blue ray player. The Samsung experts tell me its no possible even though I've been doing it for over a year. I bought the TV in July of 2016. I believe a cructhfeild tech help me set it up with blue ray so i could play my music files on my computer through my home stereo. I have a desktop computer running windows 7 pro connected with a cat 6 to modem, no Bluetooth.
